Frequently Asked Questions
How does TC664 control fan speed in a 5 V cooling system without a tachometer signal?
The TC664 controls fan speed using PWM duty-cycle output driven by an analog temperature voltage input, operating from a 3.3 V or 5 V supply. It drives 2-wire brushless DC fans without requiring tachometer feedback, simplifying system design and reducing fan and controller wiring complexity.
For a compact server board thermal management design, what is the package footprint of TC664?
TC664 is housed in a 10-pin MSOP package with a body size approximately 3 mm x 3 mm and 0.65 mm pin pitch, making it one of the most compact fan controller options available for space-constrained PCB layouts in 1U server and embedded system designs.
When should engineers consider TC664 over a discrete PWM fan control circuit for thermal management?
TC664 integrates temperature sensing input, PWM generation, and fan drive logic in a single 10-pin IC, replacing circuits that would otherwise require a comparator, RC network, and driver transistor. For designs needing automatic speed control under 5 V supply, TC664 reduces component count and board area compared to discrete approaches.
